Southeast Asia’s largest battery goes online


Sembcorp and Singapore’s Energy Market Authority (EMA) have announced the successful commissioning of a 285 MWh energy storage system in the Banyan and Sakra region on Jurong Island, Singapore.

The large-scale system features 800 high-energy density lithium iron phosphate (LFP) batteries and occupies 2 hectares of land. It is the largest energy storage system in Southeast Asia, according to Sembcorp.

“Its rapid response time to store and supply power in milliseconds is essential in mitigating solar intermittency caused by changing weather conditions in Singapore’s tropical climate,” the company said in a statement. “It can also provide reserves to the power grid, which frees up power generation plants to generate more electricity to meet demand, when needed.”

A central control system regulates the batteries' charge and discharge cycles according to grid needs. The integrated system also includes liquid cooling systems or built-in air conditioning systems to maintain optimal operating temperatures.

The February edition of pv magazine, due out on Wednesday, is devoted entirely to energy storage, with topics ranging from how battery suppliers can avoid supply-chain related policy risks, to the plans Russia hatched to be a hydrogen superpower – before it invaded Ukraine.

In addition, Sembcorp operates a 360 MW battery in the United Kingdom.
